Below are sections for each of the displays in the Living Museum of Dead Computers with the goal of writing a concise statement suitable for museum signage.

Slate Tablet

Inscribed by its contributor with the statement "Your new information technology may become obsolete". According to Wikipedia, the use of writing slates dates back to the 14th century, but became the primary tool in the classroom for students in the 1800s century and remained so until the 1930s, when pencil and paper became more common.

Leroy Lettering Guide

Before computer printers, many scientists turned to Leroy Lettering Guides to label axes and figures.

Slide Rule

Before integrated circuits made pocket calculators affordable in the 1980s, every high school math student learned to use a slide rule to perform advanced calculations.

Mechanical Calculator

The Monroe Calculator Company, founded in 1912, started out making mechanical adding machines. Electromechanical calculators, like this one, were produced through the 1960s and 1970s. This one is probably from the late 1950s and cost $595 when new. It was probably used by ecologists to calculate life tables.

Model 15 Teletype

The Model 15 teletype came into service in the 1930s and was the mainstay for electronic communications during World War II. It remained in service in press agencies until the 1970s.

Digital Equipment Corporation was an important, early Massachusetts computer company. This computer, manufactured in 1974, this computer was still in service in the 1990's with a small paper sign taped to it saying "Please God, Keep it Running".

Compaq Portable III

This 20 lb "luggable" was the closest thing to a laptop in 1987. It cost $5,000 ($10,545 in 2014 dollars) with a 20 MB hard disk. 12 MHz 80286 CPU, 640 to 2048 Kilobytes RAM. 5 and 1/4 inch floppy disk, 1.2 MB. Salmon-colored gas plasma display, 640 x 400 pixels or 25 lines by 80 characters text. Operating system: text based MS-DOS 3.31 (no GUI).

Amstrad PCW8256

Amstrad computers claimed a substantial part of the computer market in the UK, but were never common in the US. This model was sold as a personal word processor through Sears, but came with CP/M, BASIC, and Logo.

The IBM PC is perhaps the most iconic computer of all time, symbolizing the transformation from when computers moved from the backroom and office to the home. Purchased in 1983 for $4500, this computer had an 8088 processor (around 5 Mhz), 640K of RAM, and 2 160kb floppy drives.

Powerbook 100

The first modern laptop computer, which set the design characteristics that would define the industry, the Powerbook 100 has been recognized as the one of the most transformative computers of all time.

TRS-80 Model 100

The Model 100 version of the classic TRS-80 set the standard for mobile computing for a generation. It was still in service -- and in demand -- 20 years later for journalists and scientists working in remote areas due to its ability to use retail batteries (D-cells) and communicate reliably through simple telephony. The Microsoft BASIC interpreter is reputed to be the last code that Bill Gates personally worked on.

NeXT Cube

After Steve Jobs left Apple, he started NeXT to build high-end computer workstations. They were expensive and didn't achieve commercial success. Early versions, like this one, had neither a floppy nor a hard-drive and, instead, used an odd magneto-optical disk.

NeXT was ultimately purchased by Apple and its operating system, NeXT Step formed the basis of MacOS X.

Sir Timothy Berners-Lee, the creator of the World Wild Web, used a NeXT computer for software development which became the world's first web server.
